WHOOP and Oura bring sleep, recovery or readiness, and activity. A Withings scale sends weight and body composition straight into your log, and manual entries always win over synced ones.

Daily scale weigh-ins also turn on the Quality of change card on Progress: your trend split into fat and muscle, plus a water check that explains overnight jumps before you can worry about them.

If you also get InBody scans, expect two muscle lines on Progress. An InBody measures skeletal muscle, the muscle attached to bone. A scale measures muscle mass, all soft lean tissue, which runs about half again as high. They are different measurements, so FuelPath keeps them apart and you compare each line to itself.

Data syncs automatically every few hours, on pull-to-refresh, and with the Sync now button in Settings. Withings weigh-ins go one better: the scale pushes to FuelPath the moment you step off, so the reading is usually waiting before you open the app.

Some numbers land late; steps often post the full day's total the next morning. If a Habits auto row is waiting on lagging data, tap it and check it yourself; the data takes back over when it arrives.

Tap your WHOOP or Oura card on the Habits tab to open the full view: sleep stages night by night, HRV and resting heart rate trends, and your recovery or readiness history.

Sleep nights are color coded by hard bands: 7 hours or more shows green, and it steps down through yellow and orange to red at 5 or less.

WHOOP workouts sync in automatically: sport, duration, strain, calories, heart rate, and time in each heart rate zone. Find them on the WHOOP dashboard under Workouts, with 30-day, 90-day, and year-to-date analysis above the list.

Tap any session for the full read: zone-by-zone minutes plus how it compares to your other sessions of that sport this year. A recorded workout can also auto-check the Workout from your watch row on your Habits page. Connected WHOOP before workouts shipped? Disconnect and reconnect once in Settings.

Your activity can also suggest a day type: a big training day deep into a Cut with no recent refeed, or a quiet day that looks like rest, shows up as a suggestion on the day-type row of your day review. You always make the call; nothing changes until you tap Set.
